Ok, so I said I had fedora 3 in my subject, but I'm not really sure what I have. I installed fedora 2, and then tried to do a yum update to fc3. It got stuck somewhere in xorg fonts I think. I then put in the fc3 dvd and did an update, and that finished, but x didn't work. But that's not the point. The point is that I'm running ettercap (ON MY OWN NETWORK) from a debian box, and I'm getting this:

Those ports are samba (right?) and then something else, but anyways the
point is, what do I do and does this error matter?

Those are Samba/netbios ports alright.
I would check for;
1) A trojan or spyware (even somewhere on your LAN)
2) Broken (partly??) NIC card or cable, etc.
3) Driver or module that is bad.
I would try a clean install.
